Transient Response
The picture below shows the deviation of the output
voltage in response to the 50-75-50% step load at
1A/ μ s. In all tests the ZY8160 converters had the
switching frequency of 1MHz and a total of 660 μ F
ceramic and tantalum capacitors connected across
the output pins. Bandwidth of the feedback loop was
programmed for faster transient response.
